The Gems RFS series flow switch builds an extra level of reliability and protection into your equipment. Combining visual confirmation
of flow with dynamic, electronic switch operation, the RFS series cannot be deceived into indicating a positive flow situation when no
flow actually exists. Once set to a desired actuation point, the RFS will switch to a "no-flow" condition should the rotor stop for any
reason. The RFS series has easy, adjustable switch point calibration making it the ideal instrument to protect expensive electronic
equipment from coolant flow failure.

The RFS series has port sizes from 1/4" to 1" NPTF for liquid flow settings from 0.10 to 60 GPM. Featuring rugged brass, stainless steel
or polypropylene construction, the RFS utilizes a simple and reliable design suitable for operating temperatures to 212°F and line pressures
to 200 psig.
